Description

A kind of combined sleeve die nut

Technical field

The present invention provides a kind of a kind of combined sleeve six for using for loading and unloading built-up jig band special shoulder primary nut Angle spanner, belongs to built-up jig field.

Background technology

In built-up jig assembling process, achieved a fixed connection by key, screw bolt and nut between element, spanner is to tighten Or a kind of common instrument of back-out nut, suitable species, sleeve die nut need to be selected according to component structure and fixture space It is relatively conventional one kind, needs to be commonly used in assembling process.Original sleeve die nut full-length is 160CM, In built-up jig assembling process, this kind of spanner being selected the assembling of the similar structural element such as left and right angle bar, but ought need to assemble specification more During for 180,240,300 left and right angle bar or similar structure, the spanner cannot be used flexibly because of self structure limitation, need to be passed through Vibration flexible handle realizes assembly and disassembly, and spanner is at most only capable of 180 ° of rotation and discontinuous every time, assembling visual angle it is not good and It is very inconvenient in the case that screw-in thread turns is more, waste time and energy.

The content of the invention

For the problem that prior art is present, the present invention carries out local improvement by former handle and tappet head, with reference to mark Quasi- screw, nut composition not only can be used alone but also the combined sleeve die nut for using, and its function of remaining former spanner is filled Single-piece service efficiency is waved in distribution, when demand, quickly by two pieces wrench group can become simplified as special product, practical Property it is extremely strong, solve assemble profound element when box spanner fall short of, in-convenience in use problem.

In order to achieve the above object, the technical scheme is that：

A kind of combined sleeve die nut, including interior six sides tappet head 1, sleeve 2, straight pin 3, flexible handle 4, spiral shell Female A5, screw 6, nut B7, hole A8, hole B9, hole C10, hole D11, hole E12.Described interior six sides tappet head 1 is six in outside cylinder Square groove pore structure, its radial direction is provided with connection through hole at two, hole A8, hole B9.Described sleeve 2 is six square toes outside two ends Circular tube structure, and be provided with connection through hole at one group of center side of six square toes outside respectively, one end is that hole C10, the other end are Hole D11；Outer six square toes of described one end of sleeve 2 coordinate with interior six sides tappet head 1 to be installed, it is ensured that hole C10 aligns with hole A8, institute The diameter for having a hole E12, described hole C10 on the pipe of the other end of sleeve 2 stated is slightly larger than hole A8.The described mistake of straight pin 3 It is full of and coordinates press-in hole A8, through hole C10, it is ensured that interior six sides tappet head 1 has micro amplitude of fluctuation, is conducive to the biography of screwing force Lead.After described one end of flexible handle 4 passes through the hole E12 on sleeve 2, the screw thread at the end of flexible handle 4 is screwed in by nut A5 On bar, flexible handle 4 vibration but can not drop arbitrarily in the E12 of hole.

When two sets of combined sleeve die nuts are combined, the movable hand on first combined sleeve die nut After handle 4 and nut A 5 lay down, the interior six sides tappet head 1 of front end and first can on second combined sleeve die nut Outer six square toes of modular sleeve die nut rear end coordinate to be installed, it is ensured that second hole B9 of combined sleeve die nut Hole D11 with first combined sleeve die nut is alignd, and screw 6 is realized through the nut B7 that screws on after hole B9 and hole D11 It is fixedly connected.

Beneficial effects of the present invention are：There is the structure type of outer six square joints by the way that original sleeve is improved into two ends And length sleeve is designed as 180CM in the case where intensity itself is not influenceed, one combination of brand-new on interior six sides tappet head Connecting hole, while flexible handle is changed to detachable, makes the unit such as left and right angle bar that the present invention can directly in specification below 180 It is used alone in part assembling, two sets of assemblings for combining the profound element that can then meet specification 180~300.The present invention compensate for always Formula sleeve die nut awkward shortcoming in the case of insufficient space, utilization rate is high, can work as conventional sleeve hexagonal and pull Hand is used alone, and two sets of spanner Rapid Combinations can be used into deep socket when needed again, convenient and swift, safe and reliable, Resource consumption is saved to a certain extent, is an exquisiteness, practicality, is easily invented.

Brief description of the drawings

Fig. 1 is the assembling stereogram of single set combined sleeve die nut；

Fig. 2 is the assembling stereogram of double set combined sleeve die nuts；

Fig. 3 is the application schematic diagram of combined sleeve die nut；

In figure：Six side's tappet head in 1,2 sleeves, 3 straight pins, 4 flexible handles, 5 nut A, 6 screws, 7 nut B, 8 hole A, 9 Hole B, 10 hole C, 11 hole D, 12 hole E.

Specific embodiment

Below in conjunction with specific embodiment, the present invention will be further described.

As shown in figure 1, the interior six sides tappet head 1 of combined sleeve die nut is six square groove pore structures in outside cylinder, Its radial direction is provided with connection through hole at two, hole A8, hole B9.Sleeve 2 is the circular tube structure of six square toes outside two ends, and exists respectively Connection through hole is provided with one group of center side of outer six square toes, one end is hole C10, the other end is hole D11；One end of sleeve 2 Outer six square toes coordinate with interior six sides tappet head 1 to be installed, it is ensured that hole C10 aligns with hole A8, has a hole on the other end pipe of sleeve 2 E12.The interference fit press-in hole A8 of straight pin 3, through hole C10, it is ensured that interior six sides tappet head 1 has micro amplitude of fluctuation.It is living After the one end of fixed handle 4 passes through the hole E12 on sleeve 2, screwed on the threaded rod at the end of flexible handle 4 by nut A5, movable hand Handle 4 vibration but can not drop arbitrarily in the E12 of hole.

As shown in Fig. 2 when two sets of combined sleeve die nuts are combined, first combined sleeve die nut On flexible handle 4 and nut A5 lay down after, on second combined sleeve die nut the interior six sides tappet head 1 of front end with First outer six square toes of combined sleeve die nut rear end coordinates to be installed, it is ensured that second combined sleeve hexagonal is pulled The hole B9 of hand aligns with the hole D11 of first combined sleeve die nut, and screw 6 is through spiral shell of screwing on after hole B9 and hole D11 Female B7, achieves a fixed connection.

When using, according to wanting the specification of connecting element to be selected, when sleeve die nut needs built-in length to be less than During 180CM, single set combined sleeve die nut can be used directly；When sleeve die nut needs built-in length to be more than 180CM and during less than 300CM, the built-in length of single set combined sleeve die nut is not enough, then need the spanner by two sets to enter Row is applied in combination.Because the accessory structure of combined sleeve die nut is simple, easy to process and connector is standard component, therefore It is convenient to be changed after service wear, can disassembly and assembly at any time according to demand, fully demonstrated the utilization rate and composability of spanner Energy.

The present invention has been applied in the assembly and disassembly of built-up jig, convenient to use, and reflection effect is good.
